As a result of the European Commission’s concern for the status of continental waters, and as a clear reflection of the notion of water as heritage to be conserved, in the year 2000 the Water Framework Directive (2000/60/CE) was enacted, its goal being to establish a framework to protect water and the different aquatic ecosystems by requiring the Member States to achieve a good ecological status in all their waters by 2015. Like all ecosystems, freshwater ecosystems undergo physical, chemical and energy-related changes, both of natural and anthropogenic origin. These disturbances affect the organisms living in them and those who utilize their resources. Therefore, evaluating these changes has become a very important task in order to better understand aquatic systems. The study and analysis of the ecological status of these ecosystems in relation to their conservation status and water quality is thus a fundamental tool for a more efficient and rational management of their resources, that is, a management that does not threaten the ecosystem. The present guide for the identification of Spanish freshwater macroinvertebrates aims to facilitate the job of those who go to great lengths to identify them in order to then determine biotic indices. It is not the aim of this book to serve as a zoological treaty, nor does it claim to add new information on the biology or the ecology of the taxa covered. This book is, simply, a working tool explicitly designed to facilitate the identification of the Spanish macroinvertebrates and the subsequent computing of biotic indices.

This book contains 26 contributions dealing with the biology of aquatic oligochaetes and covers a wide range of topics including taxonomy, morphology, ultrastructure, embryology, reproduction, feeding biology, ecotoxicity, community studies, and species distribution. Descriptions of new taxa in tropical areas, including Amazonian forest soils, as well as overviews on the biodiversity of aquatic oligochaetes in Australia and European groundwaters, are presented. New morphological characteristics in both marine and freshwater species are described and interpreted. Laboratory studies contribute to the knowledge of oligochaete feeding biology and reproduction. The use of aquatic oligochaetes in ecological risk assessment is analysed in detail, and standardised experimental designs for studies on bioaccumulation and pollutant transfer by food are included. Finally, a number of papers present the effects of oliogochaetes on the performance of an activated sludge plant, and multivariate approaches to the spatial and/or temporal distribution and composition of oligochaete communities in many different areas of the world, from the scale of a river to the scale of the microhabitat. The broad scope of this volume is a reflection of recent rends, not only in oligochaete research, but also in general applied biological studies.

The First Edition of Ecology and Classification of North American Freshwater Invertebrates has been immensely popular with students and researchers interested in freshwater biology and ecology, limnology, environmental science, invertebrate zoology, and related fields. The First Edition has been widely used as a textbook and this Second Edition should continue to serve students in advanced classes. The Second Edition features expanded and updated chapters, especially with respect to the cited references and the classification of North American freshwater invertebrates. New chapters or substantially revised chapters include those on freshwater ecosystems, snails, aquatic spiders, aquatic insects, and crustaceans. * Most up-to-date and informative text of its kind * Written by experts in the ecology of various invertebrate groups, coverage emphasizes ecological information within a current taxonomic framework * Each chapter contains both morphological and taxonomic information, including keys to North American taxa (usually to the generic level) as well as bibliographic information and a list of further readings * The text is geared toward researchers and advanced undergraduate and graduate students

This work provides a user-friendly, species level taxonomic key based on morphology, current nomenclature, and modern taxonomy using molecular tools which fulfill the most pressing needs of both researchers and environmental managers. This key arms the reader with the tools necessary to improve their species identification abilities. This book resolves another issue as well: the mix of female and male characters used in keys to the calanoid copepods. Often, during the identification process, both calanoid copepod sexes are not available, and the user of such a key is stuck with an uncertain identification. Here, separate male and female keys to the calanoid copepods are provided for both the genera and species levels.
